S2 Sign Company

LED Channel Letters

Custom channel letter signs built in Loveland for Colorado businesses.

S2 Sign Company designs, fabricates, permits, installs, and services LED channel letters from our Loveland shop for businesses across Northern Colorado, the Denver metro area, and Colorado Springs.

You do not need to decide between front-lit, halo-lit, or combination-lit letters before you call. We help match the sign to the building, your logo, landlord criteria, viewing distance, local sign code, and budget.

Choose the light, not just the letter

Which channel letter style fits your building?

All three styles can be fabricated around a custom logo. The difference is where the light goes, how the sign behaves against the wall, and what the customer needs to see from the street.

Light through the face

Front-Lit Channel Letters

The face illuminates toward the viewer. Front-lit letters are the most common choice when direct brightness, brand color, and easy recognition from the street matter most.

  • Strong readability for motorists and pedestrians
  • Translucent acrylic faces with broad color options
  • Common for retail, restaurants, fitness, medical, and service businesses

Light behind the letter

Halo-Lit / Reverse-Lit Channel Letters

Solid-faced letters are mounted away from the wall so LEDs can create a halo around each shape. The result is architectural, but the wall surface and standoff distance matter as much as the letter.

  • Refined depth without a fully illuminated face
  • Best on walls that reflect light cleanly
  • Often selected for civic, professional, hospitality, and premium commercial spaces

Face light + halo light

Combination Channel Letters

A translucent face lights forward while a second lighting effect washes the wall behind the letter. Combination lighting is layered and highly visible, but it introduces more fabrication, wiring, and wall-related decisions.

  • Direct brightness plus architectural halo
  • Useful when both daytime depth and nighttime drama are intentional
  • Not every logo or wall benefits from both effects

S2 shop note: The best option is not automatically the one with the most lighting. It is the one that reads correctly at the actual viewing distance, fits the architecture, and can be permitted, installed, and serviced without forcing the building to do something it was never designed to do.

Individually fabricated

Each channel letter is its own small electric sign.

A channel-letter set is not printed onto one flat panel. Each letter and logo shape is fabricated as a dimensional enclosure, illuminated, wired, finished, aligned from a full-size pattern, and mounted as part of one coordinated sign.

Return The fabricated side wall that gives the letter its depth and shape.
Face Translucent acrylic, perforated day/night material, or a solid metal face depending on the lighting style.
Back + LEDs The internal surface, LED layout, wiring, and weather-management details that control light and serviceability.
Power + mounting Power supplies, patterns, fasteners, raceways, standoffs, and access planned around the actual site.

The differences between a good channel-letter set and a troublesome one often live in details customers never see at first: letter depth, face retention, seams, LED spacing, wire routing, finish quality, drainage, fasteners, mounting alignment, and future service access. We test illumination before the sign leaves the shop so brightness, color, and dark spots can be checked before installation day.

Day and night both count

A channel-letter sign has two jobs.

It has to look intentional while the LEDs are off, and it has to remain readable and evenly illuminated after dark. A sign that only succeeds in one condition is only half designed.

Daylight: letter depth, face color, return color, spacing, contrast, and the relationship to the building remain visible even when the sign is off.
After dark: LED placement, face material, letter depth, and stroke width determine whether the illumination looks clean and even.

Special face treatments

Can letters look black during the day and light at night?

Yes. Perforated day-and-night face material can preserve a dark daytime appearance while allowing internal LED light through thousands of small openings after dark. It is useful when a brand calls for black or very dark letters but the sign still needs nighttime visibility.

South Park Farma, Denver: front-lit letters with black perforated faces, fabricated and installed by S2.
Ramos Law, Wheat Ridge: color-changing day/night faces designed to read black by day and white when illuminated.

This effect is not a generic film choice that works equally well on every sign. Letter size, stroke width, face color, LED output, viewing distance, and the amount of fine detail all affect whether the daytime and nighttime appearances remain convincing.

Start with the site

Before we design the letters, we look at the building.

A channel-letter set is designed against a real wall, a real viewing distance, a real lease, and a real sign code. Those conditions often determine more than a sample photo does.

Logo geometry Very thin strokes, tight counters, tiny details, and delicate letterforms may need adjustment to fabricate and illuminate cleanly.
Frontage + viewing distance Available wall area, traffic speed, approach angle, and surrounding signs determine how large and simple the message needs to be.
Wall color + texture Contrast affects front-lit letters. Texture, reflectivity, joints, and panel patterns strongly affect halo lighting and mounting.
Landlord criteria Multi-tenant properties may specify letter height, colors, raceways, illumination, mounting zones, and approval drawings.
Local sign code Allowable sign area, projection, illumination, setbacks, electrical details, and permit documents vary by jurisdiction.
Power + access Existing electrical service, attic or interior access, lifts, awnings, landscaping, traffic, and future maintenance affect the build.

Mounting matters

Individually mounted, raceway mounted, or built on a backer?

The same letter set can look and install very differently depending on how it meets the wall. The cleanest-looking option is not always the best option for the building, and a landlord or municipality may already have a preferred method.

Individual mounting

Each letter is aligned and attached separately. This often creates the cleanest architectural appearance, but it requires careful planning for penetrations, wiring, access, and wall conditions.

Raceway mounting

The letters and much of the wiring sit on one fabricated enclosure. A raceway can reduce wall penetrations and simplify installation or future service, but the enclosure remains visible.

Backer or mounting panel

A fabricated panel can create a consistent mounting plane, bridge difficult wall conditions, organize wiring, or satisfy a property’s sign criteria.

City of Johnstown reverse-lit letters at the I-25 gateway. The daylight shadows make the individual standoffs and dimensional depth easy to see.

The project, in plain English

What does a channel-letter project actually involve?

Channel letters are a sign project, not a catalog item. The exact sequence changes with the building and jurisdiction, but the work generally follows these six stages.

Start with the address and goal

Send the project address, logo, building photos, desired opening or installation date, and what the sign needs to accomplish.

Review the site and criteria

We evaluate the building, frontage, preliminary code limits, landlord criteria, visibility, likely mounting method, and project fit.

Measure the real conditions

A field survey verifies dimensions, wall construction, electrical access, lift access, obstructions, and details maps cannot show.

Design, price, and approve

The logo is translated into a buildable sign, the mounting plan and scope are defined, and the customer and landlord approve the direction.

Permit, fabricate, and test

Required permit documents are submitted, the letters are fabricated in Loveland, and the completed sign is illuminated and checked before installation.

Install and support the sign

The sign is installed, aligned, tested, documented, and inspected where required. S2 remains available for future face, LED, power-supply, and repair work.

Straight talk about cost

What determines the price of channel letters?

Two letter sets with the same overall width can price very differently. A meaningful quote needs the address, the logo, the intended scale, and enough site information to understand how the sign will be approved and installed.

  • Number, height, depth, and total stroke length of the letters
  • Logo complexity, custom shapes, thin strokes, and fine details
  • Front-lit, reverse-lit, or combination illumination
  • Standard faces, perforated day/night faces, paint, and specialty finishes
  • Individual mounting, raceway construction, backers, and standoffs
  • Wall material, structural conditions, and interior access
  • Electrical location, power supplies, wiring route, and coordination
  • Permit drawings, engineering when required, fees, lifts, traffic control, and installation access

A budget range is useful. It lets us compare realistic approaches before time is spent developing a sign the project cannot support.

Channel-letter questions

Answers before you start.

You do not need to learn the sign trade to buy a good sign. These are the questions that usually help a project take shape.

What exactly is a channel letter sign?

A channel letter is an individually fabricated dimensional letter or logo element. Front-lit letters send light through a translucent face, reverse-lit letters cast a halo on the wall, and combination letters use both effects.

Do I need to know which lighting style I want before contacting S2?

No. Start with the project address, your logo, the building, the desired visibility, and the timeline. S2 can compare front-lit, halo-lit, and combination options against the landlord criteria, local sign code, wall, and budget.

Do exterior channel letters require a sign permit?

Most exterior channel-letter projects require municipal sign approval, and landlord approval is also common in leased or multi-tenant properties. The exact requirements depend on the jurisdiction, property, sign criteria, electrical scope, and mounting method.

Can any logo be made into channel letters?

Many logos can be translated into channel letters, but very thin strokes, tiny details, tight spaces, and delicate letterforms may need adjustment. The goal is to preserve the brand while making the sign buildable, evenly illuminated, readable, and serviceable.

Can channel letters look black during the day and light white at night?

Yes. A perforated day-and-night face treatment can create a dark daytime appearance while allowing internal light to show after dark. Letter size, stroke width, LED layout, face material, and viewing distance all affect the result.

What is the difference between direct mounting and a raceway?

Individually mounted letters attach separately to the building and usually create the cleanest architectural appearance. Raceway-mounted letters attach to one fabricated enclosure that contains much of the wiring and can reduce the number of wall penetrations. The wall, electrical access, landlord criteria, serviceability, and budget help determine the better method.

How long does a channel-letter project take?

The schedule depends on site review, design approval, landlord approval, municipal permitting, fabrication, installation access, and inspection requirements. S2 provides a project-specific schedule after the address, scope, and approval path are understood.

Can S2 repair existing channel letters?

Yes. S2 can diagnose dark letters, partial outages, failed power supplies, damaged faces, uneven illumination, and aging lighting systems. Existing channel letters can often be repaired, re-faced, or retrofitted to LED without replacing the complete sign.

Start with what you know

Tell us where the sign is going and what it needs to do.

You do not need a finished specification. The address, your logo, a rough deadline, and a sentence about the result you want are enough to begin the conversation.

  • Project address or city
  • Business name and logo
  • Desired opening or installation date
  • Landlord sign criteria, if you have them
  • A rough budget range, if one has been established
